Problems solved by technology

[0006] 1. Since the internal sealing structure is realized by the locking part, the locking part is realized by two protruding rings that are engaged, and a line seal is formed by the engagement of the two protruding rings. However, due to the small cross-sectional area of ​​the protruding rings, Moreover, the container is made of ultra-thin plastic with good elasticity and plasticity. When the container is deformed by pressure, the engagement degree of the two convex rings will decrease, so that the line seal will be destroyed, so that the stability of the inner sealing structure sex decline
[0007] 2. Also because the inner sealing structure is realized by two protruding rings that are engaged, it is more laborious to open the box cover

Embodiment 1

[0031] The improved structure of fully sealed ultra-thin food container of the present invention, embodiment is as Figure 1-3 As shown, the box cover 1 and the open box body 2 are included, the edge of the box cover 1 extends upwards to form an inner tank wall 111, and the upper end of the inner tank wall 111 is bent horizontally outwards to form a tank top 112, and the outer end of the tank top 112 The part is bent and extended downwards to form an outer groove wall 113, and the inner groove wall 111, the groove top 112, and the outer groove wall 113 form a downwardly opening annular groove 11; the box mouth of the box body 2 extends upwards to form an inner straight edge 211 The upper end of the inner straight edge 211 is bent horizontally outward to form a flat edge 212, and the outer end of the flat edge 212 is bent and extended downward to form an outer straight edge 213. The inner straight edge 211, the flat edge 212, and the outer straight edge 213 constitutes the comp...

Embodiment 2

[0036] Embodiment two of the present invention, such as Figure 6-10 As shown, the difference between it and Embodiment 1 is only that the inner straight edge 211 of the box opening compound edge 21 and the inner groove wall 111 of the groove 11 are inversely tapered with a small top and a big bottom, and the structure of other parts And the taper of the inner straight edge 211 and the groove 11 are the same as those in the first embodiment.

Abstract

The invention discloses an improved structure of a fully-sealed ultra-thin food container, which comprises a box cover and an open box body, wherein the box cover is provided with an annular groove with an downward opening, the annular groove comprises an internal groove sidewall, a groove top and an external groove sidewall, the box body is provided with a box opening complex edge comprising an internal straight edge, a flat edge and an external straight edge, and a groove sleeve is buckled on the box opening complex edge; the inner side of the external groove sidewall of the groove is provided with a lug, the lug fastens the lower end part of the external straight edge of the box opening complex edge, the external straight edge of the box opening complex edge is extended obliquely downwards and outwards, and the lower end part of the external straight edge abuts against the inner side of the external groove sidewall of the groove; and the internal straight edge of the box opening complex edge and the internal groove sidewall of the groove are matched with each other to form a cone. By using the scheme, the invention has the advantages that the internal seal structure is stable and the box cover can be opened easily compared with the prior art.

Description

technical field [0001] The invention relates to a fully sealed ultra-thin food container which can prevent food soup from leaking and has high compressive strength. Background technique [0002] Traditional sealed food containers, such as the sealed lunch boxes disclosed in Patent Nos. 86210848, 87216769, 89200752, 94222756, etc., have sealing devices composed of locking mechanisms such as buckles, press buckles, and screws, and sealing elements. These designs not only have structural Complicated, high cost and other disadvantages, and not suitable for plastic, paper fast food boxes. Patent No. 89218416 discloses a plastic blister fast food box, which uses a self-locking structure of two concave-convex steps to replace the original product's planar fit, so that after the fast food box is closed, it is impossible to open without relying on the outside, and the sealing performance is improved . But when this fast food box is subjected to extrusion deformation, lid and box bo...
